Cranking compression numbers?
Anyone know what these cars should have for cranking compression when testing? It’s a 2010 6.2l

No less than 100psi on any cylinder and less than 30% variance from highest and lowest cylinders psi.... Per Google

I know the variance, was just curious if anyone knew a rough number.... it’s clear I have have issues just trying to figure out how many cyclinders. My best is 145lbs my worst is 110. I know compression testers can even make a difference, was looking for a number I should be aiming for

Not sure if this helps but when my motor was freshly rebuilt, before first firing, I was getting around 180

mine put out 180 to 185 on all at 5 cranks, 200 to 205 on all at 7 cranks. 37k miles
Not a perfectly accurate measure that everything is good.
